If your needs require more inputs/outputs than you currently have, we recommend considering [another controller](https://edingcnc.com/product-category/controllers/).

Otherwise, we offer our [RLY8 device](https://edingcnc.com/product/rly8-io/) which adds 8 relay outputs and 8 opto-coupled inputs. The RLY8 device is compatible with **controllers that support MODBUS**, such as the CNC7xx and the iCNC600.
